Concept
The façade restyling for the Marposs Japan Headquarters began with a precise condition: an anonymous 1970s concrete office building with a solid structural frame, but little architectural identity. Rather than replacing it, the project set out to work with what already existed, transforming technical constraints and structural limitations into the starting point of a new architectural expression. The intervention restores dignity, presence and recognizability to the building without demolition, proposing a more sustainable and intelligent approach to renewal.
Developed in collaboration with the Japanese company Asahi Glass, the project combines technical performance with cultural reference. The design draws inspiration from the bugnato a diamante typical of Bologna, the city where Marposs was founded. This historical motif becomes the conceptual bridge between Italian architectural heritage and the Japanese context, bringing a fragment of Italian identity into the urban fabric of Tokyo. Rather than quoting the past literally, the project reinterprets this geometric tradition through a contemporary façade system defined by precision, rhythm and repetition.
The new envelope was made possible through the use of GRC, glass reinforced concrete, a material whose technical qualities allowed for a custom-designed molding system. Each module was carefully calibrated to align with the proportions and cadence of the existing structure, ensuring that the new façade did not simply cover the old building, but established a coherent relationship with it. In this sense, the project is both corrective and generative: it responds to the constraints of the original construction while producing a new visual order.
The glazed portions of the façade introduce an additional layer of transformation. Their smoked finish creates a superimposed order that partially conceals the pre-existing elevation, softening its anonymous character and giving the building a more abstract, controlled image. This interplay between opaque white modules and dark glass generates contrast, depth and clarity, allowing the façade to shift from a purely technical enclosure to an identity-bearing surface.
Within this new composition, the large blue Marposs logo stands out sharply against the clean white field of the façade modules. Brand presence is not treated as an applied graphic element, but as an integral part of the architectural composition. The building becomes an expression of corporate identity through proportion, materiality and visual precision rather than through excess.
More broadly, the project represents an effective example of retrofit as architectural strategy. It shows how an existing building of modest appearance but sound construction can be reimagined through thoughtful design, avoiding the economic and environmental costs of demolition and reconstruction. By bringing together Italian formal memory, Japanese material technology and a careful reading of structural rhythm, the intervention transforms an ordinary building into a precise and recognizable architectural presence.
